CrystalClear, D-Solv9 Pond Cleaner, 64 Ounces

I have been have algae issue with my pond due to the hot summer and direct sun light. I even have UV light running on my pond. With that being said I use d-Solv9 to clear up my algae pond and now it crystal clear. I can see the bottom again in a 4 foot deep pond. It only took one day for my pond (8000 gallons). I know place the recommend amount every week to keep my pond looking at it best. Well worth the money.

Very disappointing-the first application worked great, we thought we had finally found a product that would work in our pond. However soon after (1-2 weeks) we're right back where we started and future applications provided no benefit. Went on to buy another product that supposedly pairs with it; to no avail, just more money spent with no results. Don't waste your money.

Cleaned my pond in one week and I've been struggling with that angel hair algae for several months. I don't know why it got so out of control, but after a recommendation from my local pond place, this is the only thing that worked. I do this every quarter and use a less potent pond cleaner for weekly treatment. This even cleared up the lines in the filter and the hoses hooked into the UV light. Great stuff to beat tough, recurring algae.

Working very well in our pond. Very concentrated so you do not have to use a lot. Had definitely helped with the algae problem we were having. Our pond is in full sun so it is very prone to algae growth. I will continue to use and plan to purchase again once this bottle is empty.

Did not help clear the floating algae. Cleaned filter and bottom did not help either

this is without doubt the best pond cleaner that i have ever used .clears pea green alga water within 24 hours or less.i have spent hundreds of dollars trying other products and wasting countless hours draining my pond only to have it turn green again withing a couple of weeks or less.

Did not do what is intended to do. Followed directions and unsatisfactory results.

Works fast and does the job. Just be sure not to use it in the morning when the oxygen is at the lowest to not stress your Koi.
